SPLIT-RIM LOCK Ann RELEASE.

Application inea April is,

To all whom t 'may concern:

Be it known that l, HARRY R. lllALsBARY, a citizen of the United Statesresiding' at Frankfort, in the county ot' Clinton and State of indiana, have invented certain new and useiful llifnprovenients in Split-Rim Locks and Releases, oli' which the following is a specification. j

This invention relates to a combined split -rim lock and release therefor, one feature "of thef'invention being the'provision of a rotating locking mechanism yfor holding the ends ot a split rim together, said lock and parts of the rim having interlocking parte which hold the lock against casual operation. 4

A Lfurther feature of the invention isfin so constructing the interlocking parts of the lockA and'ri'm that an eiidwise movementwill be imparted to one end of the lsplit rimas the locking mechanism is operated Yfor releasing the end of the split rim. y

A Ytui-ther feature oi the invention is the provision oi means on the locking mechay nism for elevating one end ot' the split rim and releasing it ilroin,r the opposite endhoi the split rim `when ythe locking mechanism is rotated, said .releasing i'necl'ianism being so constructed that when the locking mechanism is being turned to locked positionendwise movement will be imparted to one end oll the rim. e

@ther objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specication.

.in the accompanying drawing Figure 1 is a top plan view'otk a pair ot split rim ends for automobile wheels showing` the same in locked position,

Figure 2 is an edge elevation thereof,

LFigure 3 is a view similarut'o Figure 1 with the locking mechanism operated to elevate one end o't the split rim, v

Figure Llis an edge elevation thereof,

Figure 5 is a bottom plan view ot the combined locking and releasing member removed trom the rim, p

Figure 6 is a sectional viewthrough the rim and locking mechanism,

Figure T is a plan view of combined wrench and tire tool,r and Figure 8 :is an edge elevation thereof with parts broken away.

Referring to the dicate the meeting drawings, 1 and .35 inends o'f-a split rim 3,

` the 192i. serial No. 461,774.

such as is used for mounting tires upon a vvehicle wheel, the end 1 having a tongue 4L which projects into a notch 5in the end 2, said tongue resisting lateral movement of the end .Zywith respect to the end 1. Mountf. ed over the inner tace of the tongue 4c and 'projecting a distance beyond the free edge thereof, is' a plate 6the tree end of which overlaps the end 2, and in rorder to 'securely lock the two ends of the rim together a locking end 2 and in position to overlap the plate Gwhen the memberis turned Lto locking position. body` of 'the locking member and has its ends upset and fitted in counter sunk openings 9 and 10 in the locking member and rim 3.`

The locking member 7 is provided with a cam portion 11 in the under face of Which ris termed a recess 12 thereby constituting a wall 13 which limits the swinging movement off the locking member in one direction, and ashoulder 14 against which the end of the plate 6 abuts when the locking member is in locking; position. `.lllie outer end of the shoulder .14e -is curved, as shown at 15, so thaty the locking member can be readily rotated when moved to unlocked position: however, said curved portioiiis so arranged that the endl will be loosened and moved away :from the end 2 as the locking member 7 is being turned to its unlocking position.

The outer face of the cam portion 11 is also provided with spiially arranged inclined faces 1G and 17wliich being wedgeshape, and in stepped relation with each other, will successively pass below the projecting end ]K)late(` and the tongue 4, said parts ridingupthe incline-d faces and moving` the end 1 out of 'registration' with, the

end 2 of the rim when the loc-king member is rotated to unlocked position. ,in moving the locking member to unlocked position it is rotated until the dat tace 18 thereof registers with the end ot the plate 6, after which a tool or other instrument .is entered between the ends 1 and 2, andthe end 1 lifted so l the locking member, particularly that portion immediately around the rivet is extended upwardly a distance and provided with afilattened suriace to torni a nut 1f) so 'member 7 is pivoted tothe inner face of A rivet k8 passes through the i .llO

that a wrench or other. tool maybe readily applied thereto for moving the locking member to locked or unlocked position. The locking member 7 at a point substantially diametrically opposite the recess 12 is provided with a curved shoulder 2O which acts as a cam for forcing the end into position to register with the end 2 when said end 1 is forced outwardly.

When the rim 3 is fully collapsed the end 1 proj ectsarlistance inwardly past the locking member and, 1when a new tire is placed aroundwtlie rim said end must be forced backto position, and to more readily accomplish' this result the face of the rim adjacent the end 2 wis provided with a plurality of serratioris on ribs 21 so that by entering the endofa tool below thecollapsed end 1 and giving a pryingfaction thereto the end of the tool will engagefwith the serrations, and prevent slipping actionpfoVt-he tool. l* Any suitable tool yor yinstrument may be provided for operating,the` locking member 7 and Jfor prying on the.A endl of thefrim, but a preferred form ofxdevicelislshown inliigures 7 and S, which lcornprise's acom'bined prying tool and wrench consisting ot' an elongated khandle portion 22 having in its length a, bent-up portion 23 for forming a socket, they closed end othebent-upnportion having a slot l24rcut thereinl said slot extending into the closed. end and fone vertical wall andvby entering the nut 19in the slot the tool may be used las, a. wrench. One `end of the vtool is providedwith ahead 25 which is bifurcated at its, freejiend to form arms `26, the head portiondand armsy being bent out of align" ment with the remainder of the handle portion, asy best shown in Figure 8, and serves a double purpose, that of lifting the end 1 or' thezrimabove the locking-.member 7 and the nut 1 9y thereon, and as a pry for returning the endlvto; Aits initial position.

Alin releasing` the locking mechanism the tool ,is placed over the locking member 7 and the nut 19 thereon entered in the slot 24: after ,which the tool is operatedas a wrench andl the locking member rotated. Asthe locking member is rotated to lift the end 1 of the rim the shoulder 20 comes in contacttwith the end of the plate 6 and forces the ends 1 and 2y apart sufficiently to brealrzgconnecltions between the two and as the face 1.6 comes in contact with .the projecting end oi `the plate t3, said plate will ride up said tace and thereby elevatey the end 1. As theloclring member 7 continues to rot-ate the inclined tace 17 passes below the tongue 4, consequently said tongue will ride up the inclined face 17 and elevate the end 1 of the rim a distance above the end 2; as shownl in Figure 4. ll`he tool is then removed from the nut 19 and the arms 26 thereof introduced below the end 1 on opposite sides ot the locking member, the head portion 25 then resting above the nut 19. yThe outer end of the handle member 22 1s then lowered, which in view of the fact that the headv i heldagainst slipping, consequently the force applied will readily expand the rim to its initial operative position. o

lt will be understood, of course, that at the time of raising or lowering the end 1 romengagement with the end 2 the locking member 7 is turned untilthe flat `tace 18 registers with theend of the plateand after the rim has been expanded and the lend 1 forced downwardly into registration with the end 2 the tool is again applied to the nut 19 and the locking member 7 turned 'in the opposite directiom thereby disposing the cam portion over the plate 6, the movement of the locking member 7 continuing until the walll strikes the edge ofthe plate 6. As the shoulder 14 and end of the plate 6 are both flat or extend substantially in a straight line7 the locking member will'be securely locked, against casual operation owing to the tact that it is necessary to exert a slight endwise movement to the end 1 in releasing the locking member from the plate 6.

Having thus :fully described my said invention, what Iclaim as new and desire to secure by Letters Patent, is:

1. rEhe combination with the meeting ends of a split rim, of a revolving locking member carried by one of said ends and engaging parts of the opposite end tor holding' the same` in locking positiomand stepped on the locking member for releasingrani'd elevating one of said ends when the locking member is rotated in one direction. v

2. The combination with the meeting ends of a split rim, of a revolving locking member rotatably securedto Aone of said ends, a plate secured to theopposite end, and stepped on the locking kmember for engaging said plate and elevating the end of the rim to which the plate is attached when the locking member is rotated 4 in one direction.

3. rllhe combination with the meeting ends of a split rim, one of said ends having a tongue and a. plate mounted thereon7 and the opposite end havinga notch for the reception of said tongue, of a locking Ameinber rotatably mounted upon the end having the notch, means on the lock-ing member 'tor imparting endwise movement to the ends of the rim when rotated, and additional means on the locking member for engaging successively said plate and tongue for elevatlio ing the end of the rim having said tongue and plate to a plane above the opposite end.

4. A combined locking` member` and release for the ends of a split rim, comprising a rotating member, a cam portion for interlocking with one of the ends of the rim, and inclined portions adapted to engage and ele vate one of the ends of the rim when the locking member is rotated.

5. A combined locking and releasing member for the ends of a split rim, comprising a rotatably mounted member having a cam portion in the under face of which is formed a recess for engagement with one of the ends of the rim, means on the locking` member for imparting endwise movement to the ends of the rim when the locking member is rotated, and inclined surfaces for successive engagement With one of the ends fork elevating said end When the locking 20 HARRY R.
